Radiation therapy alone or in combination with surgery in the treatment of carcinoma of the esophagus.

The role of radiation in the treatment of squamous cell carcinoma of the esophagus was examined in a review of 74 patients treated with curative intent between 1974 and 1981. Aspects studied included the pattern of failure, the use of radiation as a surgical adjuvant, achievement of palliation, and the presence of technical or clinical factors predicting for a better outcome. The group was divided into 9 patients irradiated after esophageal resection, 14 patients irradiated before resection, and 51 patients treated with radiation and no resection. Median and 2-year survival rates among 51 patients treated by radiation without esophagectomy were 8.8 months and 11%, whereas they were 9.7 months and 0% in patients treated by radiation followed by resection, and 9.5 months and 28% in patients undergoing resection followed by radiation. Local failures were suffered in 28/51 patients treated without esophagectomy with rates of 2/4, 7/10, 7/15, and 5/10 after 50-55 Gy, 55-60 Gy, 60-65 Gy, and 65-69 Gy, respectively. Although prognosis for patients presenting with unresectable disease remains poor, a somewhat better outcome may be expected in patients treated with postoperative radiation after potentially unfavorable resections. Other predictors include sex and disease stage.
